Table 6-17 User FIR File Download Trouble – Symptoms and Causes
Symptom Possible Cause
ERROR –321, Out of memory
There is not enough memory available for the FIR coefficient file being
downloaded.
To solve the problem, either reduce the file size of the FIR file or delete
unnecessary files from memory.
ERROR –223, Too much data
User FIR filter has too many coefficients.
The filter specification cannot have more than 1024 taps (2048 coefficients
for a complex filter).
